How to use this calculator
Enter the image’s pixel dimensions and the print resolution. The print size and megapixels are calculated. Or enter a print size to find the required pixels.
Formula
print size (in) = pixels ÷ DPI
Example
6,000 × 4,000 px at 300 DPI → 50.8 × 33.9 cm (20 × 13.3 in), 24 MP.
Frequently asked questions
What DPI should I print at?
300 DPI for high-quality photo prints viewed up close; 150–200 DPI is often fine for larger prints viewed from further away.
How big can I print a 24 MP photo?
A 6,000 × 4,000 pixel image prints at about 50.8 × 33.9 cm (20 × 13.3 in) at 300 DPI.
Are DPI and PPI the same?
They are often used interchangeably. Strictly, PPI is image pixels per inch and DPI is printer ink dots per inch.
